Respiratory complications following COVID-19 in athletic populations: A narrative review

Athletes typically experience a mild-to-moderate, self-limiting illness following infection with the novel severe acute respiratory syndrome coronavirus 2. Some athletes, however, can develop prolonged symptoms, with breathlessness, cough, and chest tightness impacting return to training and competition. In athletes with persistent cardiopulmonary symptoms following COVID-19, focus is usually placed on the identification and characterization of cardiac complications, such as myocarditis. In this review, we focus on summarizing the literature assessing pulmonary complications and physiological consequences associated with COVID-19 illness in athletes. The review also provides recommendations for clinical assessment of the athlete with pulmonary issues following COVID-19 and directions for future research.
